Recommended ports, should be used for DeviceComm

The port number functions as the TCP/UDP source port number for outgoing packets.
Packets sent to the unit with this port number are received to this channel. The port number
selected is the Incoming TCP/UDP port and Outgoing TCP/UDP source port. Port 0 is used
when you want the outgoing source port to change with each connection.
If the port number is set to 0, the initial value of 5000 will be used to actively establish a
connection. Each subsequent connection will increment the number by 1. When the port
number reaches 7999, it will wrap back to 5000.
The automatic port increment feature must only be used when this device is the one
initiating a connection using TCP. The port must be set to a non-zero value when this is a
passive device or when UDP is being used instead of TCP.
